In pictures: top garden tips for March

Bunny Guinness says: If you have just put up fencing and it is looking rather too new, and you want to quickly turn it into that soft, silvery-grey finish, here is a simple way to do it. Put a ball of wire wool about 1in (2.5cm) in diameter into a litre of distilled malt vinegar and leave it for at least 24 hours. After this it is ready to use. Brushing on the solution works best but the effect takes a few hours to work – after this the wood will have changed colour to a silvery grey. It works best on pressure treated sawn timber (“prepared” or planed).
